ABSORBING DEVICE FOR SOLAR ENERGY

摘要

PURPOSE:To improve thermal efficiency by arranging a reflector and an incident window under the absorling plate placed under a heat accumulator the upper part of which is covered with adiabatic material. CONSTITUTION:An incident window 19 for solar energy E is equipped in front and closed by a transparent plate 20. On the internal side is equipped a relfector 17, above which a heat accumulator 14 having an absorbing body 11 on the lower surface is arranged, covered by adiabatic material 15 and is provided with a pipe 16 for pumping out thermal energy. The absorbing body 11 is made up of stratified porous plates 11a-11c where a selective absorbing surface is formed on the lower side and a reflective surface is on the upper side.
